C Correct answer
Explanation

Total number of balls = 4 red + 3 white = 7. The probability of drawing a white ball is the number of white balls divided by the total number of balls, which is 3/7.

AI explanation

The total number of balls in the bag is the sum of red and white balls, which is 4 plus 3 to give 7 balls. The probability of drawing a white ball is the ratio of white balls to the total number of balls. With 3 white balls available, the required probability is 3 divided by 7, which equals 3/7.
